Abstract

The objectives of this study were to analyze the width changes about the head and tail ends of the slab occurring during vertical–horizontal rolling using finite element (FE) analysis, and to derive an appropriate short stroke control (SSC) model for vertical–horizontal rolling based on the results of analyses. The relationship between the process variables and slab deformation about the head and tail ends, including width shrinkage and length of width shrinkage, was derived using the linear regression method. From considering the amount of slab deformation, an advanced SSC model for vertical–horizontal rolling process has been developed. The proposed SSC model was verified via an FE simulation. Vertical rolling simulations were performed using the roll gap that was calculated via the respective SSC model for each steel slab. Horizontal rolling simulations were also conducted. Cropping lengths about the head and tail ends that were regulated by width control standards of the specific work site were compared.
